Still at Expo 85 today and for a few days to come. Inside the post office building seen already was a counter to buy special Expo 85 stamps, and to get special cancellations and other souvenirs of the event. I've managed to misplace the stamps I bought there but they're likely to turn up some day. That's one of the advantages of having so much stuff stashed away - when it turns up it will seem like an early Christmas present!
